Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981432, here are decompositions:

13 + 981419 = 981432
41 + 981391 = 981432
59 + 981373 = 981432
113 + 981319 = 981432
131 + 981301 = 981432
149 + 981283 = 981432
191 + 981241 = 981432
211 + 981221 = 981432

Showing the first eight; more decompositions exist.
